BOWLING PIN.

Application filed Ma 7, 1926, Serial The present invention relates to improvements in bowling alley pins, such as ten pins and duck pins, and has reference more particularly to an improvement over the bowling pin disclosed in Patent No. 1,585,123,

granted to me May 18, 1926.

One of the important objects of the present invention is to provide a bowling pin of the type disclosed in the aforementioned application wherein the inner ring is provided with means for permanently securing the same on the bottom of the pin against accidental displacement.

A further object is to provide a bowling pin wherein said ring provided with means whereby an interlocking association between the rubber protector ring and said inner ring is provided.

A still further object is to provide a bowling pin of the above mentioned-character which is simple in construction, inexpensive, strong, and durable and further well adapted to the purpose for which it is designed.

Other objects and advantages of the invention will become apparent during the course of the following description taken in connection with the accompanying drawing.

In the accompanying drawing forming a part of this application and in which like numerals designate like parts throughout the several views:

Figure 1 is a sectional view of the metallic and fiber rings which encircle the shank portion of the pin, and also showing the rubber protector ring, and the manner in which the prongs are clinched in the pin.

Figure 2 is a side elevation of the metallic ring and the fiber ring associated therewith.

Figure 3 is a vertical sectional view taken approximately on line 33 of Figure 2, and

Figure 4c is a transverse section through the upper portion of one of the prongs.

In the drawing wherein for the purpose of illustration is shown the preferred en bodim'ent of my invention, the numeral 1 designates the bowling pinwhich is preferably formed of maple wood and may be either a ten pin or a duck pin. The lower end or base of the pin is under cut as illustrated at 2 and extending downwardly therefrom is the central shank portion 3. An annular groove 4 is formed in the under cut portion 2 and the same extends around the upper portion of the reduced shank 3 in the No. 107,436. Renewed July 26, 1928.

manner as is clearly shown in Figure 1, and as is further set forth in my aforementioned gatent No. 1,585,123 granted to me May 18,

Adapted to fit over the shank 3 is the inner ring 5 which is formed of any suitable composite material preferably fiber. Cooperating with the fiber ring 5 is the metallic ring 6. These rings are of the same width and for the purpose of securing the same together, the metallic outer ring 6 is provided with the inwardly projecting protuberances 7, the same being adapted to fit in suitable openings 8 provided therefor in the fiber ring 5. This construction is more clearly shown in Figures 1 and 3 of the drawing. Any number of these protuberances and cooperating openings may be provided as is necessary for securing the two rings together.

Extending upwardly from the upper edge of the metallic outer ring 6, are the series of prongs 9. The upper portions of the prongs are bent along their longitudinal centers so that the upper portion of each prong is arched or substantially U-shaped in cross section as shown at 10 with reference to Figure 4 of the drawing. The upper end of each prong is furthermore beveled as illustrated at 11 so as to provide a relatively sharp edge on each prong to facilitate the driving of the prongs into the base of the pin and to further aid the prongs in being directed inwardly toward the center so as to become clinched in the pin in the manner clearly shown in Figure 1.

The provision of the prongs on the upper edge of the metallic ring 6 will provide a means whereby the rings will be properly secured around the shank 3 against accidental displacement from the pins.

Cooperating with the aforementioned ring is the outer protector ring 12 which is formed of rubber, and this ring is adapted to be vulcanized to the outer face of the metallic ring 6. The upper portion of the metallic ring 6 is further provided with the cut out portion 13 and these out out portions form key ways for the adjacent portions of the rubber protector ring 12 whereby an interlocking association of the rubber protector ring with the metallic ring 6 is formed.

The rubber protector ring is provided with the downwardly beveled upper face 14 for cooperation with the undercut portion 2 of the pin 1, and this ring'is further provided with the upwardly extending annular rib 15 on the inner portion of the beveled face 14 adjacent the inner edge of the rubber protector ring and this rib is adapted to be disposed with the annular groove 4 together with the upper portion of the liberand metallic rings 5 and 6 respectively.

As the purpose and construction ofthe rubber protector ring is fully covered in my Patent N 0. 1,585,123 granted to me May 18, 1926, a further discussion thereof in this case is not thought necessary.

The provision of the prongs on the metallic ring 6 will securely hold the same in position on the bottom of the pin around the reduced shank 3 and there will be no possibility of any of the rings becoming disengaged from the bottom of the pin when the parts are once assembled.

While I have shown the preferred embodiment of the invention, it is to be understood that minor changes in the size, shape, and arrangement of parts in, y be resorted to without departing from the spirit of the invention and the scope of the appending claims. 7

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. A bowling pin having a central reduced shank portion formed on the bottom thereof, a metallic ring encircling said shank, securing means for said ring, a'rubber protector ring encircling the aforementioned metallic ring, said metallic ring being provided with cut out portions forming key ways for interlocking association with the rubber pro tector ring.
